to Clairify, the Supercharger kits for the M20 are £3K, thats the charger, brackets, tensioner, pulleys and oil supply setup( and oil) , plus a custom alloy intercooler, all you need do is plumb in the parts using Samco or whatever you wish to use
I've not "done" that part of the kits as most will have their own ideas on how that is best achieved.
A chip and RRFPR is required, or a standalone/piggyback of some sort, again, options are out there to suit all wallets, happy to advise on that and supply a soloution if required.
